on a stone and straight edge for cutting letters or other figures in the stone, adjustments of said member 7 being readily effected by loosening and tightening nut l0.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modiiication without departing from the spirit of the invention.

I, therefore, do not wish to be limited to the exact details' of construction setiorth, but

Iavlng described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. A device of the class described comprising a straight edge; a guide rib on said straight edge; a cylindrical block slidable on said rib; a bevel angle member slotted to lit over said block and bent downwardly to form an abutment adapted to fit against said straight edge to position said member at right angles to said edge; and a binding nut carried by said block and adapted to secure said bevel angle member in adjusted positions, substantially as described.

device of the class described comprising a straight edge; a dove-tail guide rib on said straight edge; a cylindrical block slidable on said rib and provided with a threaded stud; a bevel angle member slotted to fit over said block and bent downform an abutment adapted to fit against said straight edge to position said right angles to said edge; and a binding nut carried by said stud and adapted to secure said bevel angle member in adjusted positions, substantially as described.
